Debuting in 1936, The Green Hornet is an American radio adventure series featuring the adventures of Britt Reid, a newspaper publisher who turns into a masked vigilante at night. Originating from WXYZ station in Detroit, the series was broadcast by Mutual Broadcasting System and later by the ABC Network until 1952.

The Green Hornet and his chauffeur Kato were known as outlaws, allowing them to infiltrate criminal operations in the city. Notable actors who played the Green Hornet include Al Hodge, Donovan Faust, Bob Hall, and Jack McCarthy, while Kato was played by Tokutaro Hayashi, Rollon Parker, and others.

The show used classical music for its theme and bridges between scenes, and its unique storytelling made it "one of radio's best-known and most distinctive juvenile adventure shows." The Green Hornet was related to another popular radio series, The Lone Ranger, making the Green Hornet that character's grandnephew.
